A small succulent bush 25-30 cm. high in the plants seen. Main stems 

 6-14 mm. tliick, branches 6-10 mm. thick; teretCj usually with an annular 

 constriction at the nodos^ with internodes 1-3 cm. long, glabrous, at first 

 green or reddish-brown^ becoming pale grey with age. LeaYCs of two kinds. 



two pairs (one pair of each kind alternating) forming the growth of one 



itl 



wiin minute 



greea 



year ; soft and pnlpy, glabrous, when young covered 

 (not crystalline) ghttering watery papilkc, which dry up with age, tho^e on 

 the keel at the apex larger than the rest, but quite obtuse, not' at all pointed, 

 of a rather dull dark green or reddish ; one kind free except at the YcrY 

 b:ise, where they are united for their own thickness (but not more) around the 

 stem, widely recurvcd-spreading, 2-5 cm. long, 6-10 mnu broad and 6-8 mm, 

 thick at the base, tliencc tapering to a subobtuse pointj concaYe-chamielled 

 abovej obtusely keeled beneath; the other kind united below into a cylindric 

 body 2-3 cm. long and 7-11 mm, thick, similar to or scarcely distinguish- 

 able from the internode o£ stc^m se|)arating it from the pair of leaves below 

 it, \vith the terminal part of the leaves free, widely spreading or recurving, 

 2^-5 cm. long, 3^-6 mm. broad and as much in thickness at the base, Ycry 

 slightly tapering to a subobtuse pointy slightly concaYe-channelled or flattisl 

 above, obtusely keeled beneath. Flowei's unknown. 



Little Namaqualand. Slopes of the pass between the Stinkfontein 

 Plateau and Chubiessis, Pearson^ 6200 ! 



Described from living plants collected and sent to Kew 

 H. W. Pearson in 1911. They have not yet flowered.

Prof. H. 



This speci(*s is allied to M, cognatvm described below, and by reason of 

 the constrictions at the nodes of its stems, leaves, and mode of growth is 

 evidently closely related to M. monUifonnc^ Ha>v. on the one hand, and on 

 the other to M. mitralum^ MarL^ il/. fvoainuim^ and M. dlssitum described 

 here, so that the whole of these species belong to one and the same group.
